HINGE.

SEEOIEICA'EIQN formingpart of Letters Patent No. 684,726, dated October15, 1901. Application filed June 8, 1899. Renewed March 20; 1901. SerialNo. 52,082. (No model.)

To aZZ whom it may concern.-

Be it known that I, CARLETON SAW YER, of Foxboro, in the county ofNorfolk and State of Massachusetts, have invented certain new and usefulImprovements in Door Butts or Hinges, of which the following is adescription sufficiently full, clear, and exact to enable those skilledin the art to which it appertains or with which it is most nearlyconnected to make and use the same.

This invention has relation to that kind of door'butts or hinges thatare adapted to be adjusted to adjust the door in case of shrinkage orsettling of the d0or-casing so as to interfere with the proper operationof the door.

It is the object of the invention to provide an improvement in hinges ofthe class mentioned which shall be of the greatest simplicity inconstruction and the embodiment of the maximum degree of efficiency andusefulness.

The invention consists of a door butt or hinge embodying in itsconstruction two leaves, each provided with knuckles of commonconstruction, a pintle extended through the knuckles and screw-threadedin one part to receive a thumb-nut turned on the said screw-threadedpart, so as to afford a bearing for the washer upon which the knuckle ofthe door-bearing leaf rests, the said washer being connected with theopposite leaf to prevent it from turning and so keep it from to ruingthe nut from its adjusted position, all as recited in the appendedclaim.

Reference is to be had to the annexed-drawings, and to the lettersmarked thereon, forming a part of this specification, the same lettersdesignating the same parts or features, as the case may be, whereverthey occur.

Of the drawings, Figure 1 is a front View of my improved door hinge orbutt. Fig. 2 is a horizontal sectional View of the same, taken on a linerunning through the hinge just above the washer.

In the drawings, a designates the leaf of the hinge, which it may besupposed is attached to the door casing or jamb. b designates the leafattached to the door. Each leaf is provided with the ordinary knuckles aZ), and a pintle 6 extends through the knuckles, as usual in theconstruction of ordinary door-butts, excepting that the pintle at onepoint in its length is screw-threaded, as at d, to receive a thumb-nute, and for this purpose the knuckle b of the leaf b is somewhatshortened. The thumb-nut 6 may be milled on its outer surface, asshow.n,'so that it maybe readily turned on the pintle up or down.

f designates a Washer interposed between the knuckle of the door-bearingleaf 1) of the hinge and the nut e and provided with a bifurcatedextension g at one point of its periphery or circumference, thebifurcation being arranged astride the edge of the leaf a, as indicatedat h, so that when the door-bean ing leafb is swung to and froupon thewasher the latter will not be turned or moved circumferentially on thepintle, so as to in any degree disturb the position of the adjusting nuta. At the same time the washer is free to move up and down with the nut,the bifurcation slidingalong the edge of the leaf a.

This improvement is provided, primarily, for adjusting the door upon thehinge, so as to secure a proper operation of the same if the door-casingshould shrink or settle or in case the door should sag, so as to strikeupon the door-sill or other part of the door-frame. By adjusting the nute upward on the pintle c the door can be brought into proper positionwith out removingit from its hinges. In order, as before stated, toprevent the not from being moved out of its adjusted position, thewasher f is prevented from turning by looking it with the leaf on of thehinge secured to the doorcasing.

Of course otherequivalent means of securing the washerf against turningwill answer the purposes of my invention; but it is essential theretothat the washer should be locked against turning with the door-bearingpart of the hinge when the door is swung to and fro.

It will be seen that my arrangement permits the pintle to be lockedpermanently in position, since no movement of the same is required ineffecting an adjustment of the hinge.

Having thus explained the nature of the invention and described a way ofconstructing and using the same, though without attempting to set forthall of the forms in which it may be made or all of the modesiof its use,it is declared that what is claimed is- A door butt or hinge embodyingin its construction two leaves each provided with one or more knuckles;a pintle having a screwthreaded portion on which a knuckle of one of theleaves may slide; a nut turned upon the screw-threaded part of thepintle below i said knuckle and constitutingasupport therefor; and awasher interposed between this knuckle of the hinge and thenut, the saidwasher being slidingly connected with or locked to the other leaf of thehinge, whereby said washer is held against turning and the 15 nutleftundisturbed in position when the door is swung to and fro.

In testimony whereof I have signed my name to this specification, in thepresence of two subscribing witnesses,this 20th day of 20 May, A. D.1899.

CARLETON SAWYER.
